Internet Mobility 4x4

Mobile IP protocols allow mobile hosts to send and receive packets addressed with their home network IP address, regardless of the IP address of their current point of attachment in the Internet. While some recent work in Mobile IP focuses on a couple of specific routing optimizations for sending packets to and from mobile hosts [Joh96] [Mon96], we show that a variety of different optimizations are appropriate in different circumstances. The best choice, which may vary on a connection-by-connection or even on a packet-by-packet basis, depends on three factors: the characteristics the protocol should optimize, the permissiveness of the networks over which the packets travel, and the level of mobileawareness of the hosts with which the mobile host corresponds. Of the sixteen possible routing choices that we identify, we describe the seven that are most useful and discuss their benefits and limitations. These optimizations range from the most costly, which provides completely transparent...
